If you want some bomb-ass Hakata-style tonkotsu ramen, get this stuff.

Looks like it's out of stock right now on amazon.com, but it's available on amazon.ca.

I lived for a while in Hakata and went out for ramen at an entirely unhealthy frequency, so I've got some cred lol. This stuff isn't the same, but it's by far the best ramen broth I've had at home.

I haven't tried too many different noodles, but so far this has been the best. Kinda steep price per bowl tho, so I only use them once in a while. You might be able to get better, maybe fresher ramen noodles from a local Asian grocery store.

With that combo, you've got the core of a damn good bowl of at-home ramen that you can make in 5 minutes. See if you can find some pork belly, cut into slices or hunks (your preference), add whatever you use for garnish and you've got a cheap bowl of ramen you could probably justify charging money for.
